Red Rocks Amphitheatre (also known colloquially as simply Red Rocks) is an open-air amphitheater in the western United States near Morrison, Colorado, approximately ten miles (16 km) southwest of Denver. It is owned and operated by the city of Denver. In addition to several other large sandstone formations nearby, the venue is best recognized by its two massive monoliths, named "Ship Rock" and "Creation Rock", as well as the smaller "Stage Rock", which together flank its 9,525 capacity seating area and naturally form the amphitheater. While the venue is primarily known for hosting concerts and music festivals, other events of various types and sizes are held throughout the year.

In 1957, the American Institute of Architects selected Red Rocks to be Colorado's entry at the National Gallery of Art for the AIA's Centennial Exhibition. In 1999, after Pollstar magazine awarded Red Rocks the annual honor of being the best small outdoor venue for the eleventh time, the magazine changed the name of the award to the "Red Rocks Award" and removed Red Rocks from the running.

Construction began in October 2020 to replace the existing stage roof and expand the structure's rigging capacity; the work was completed the following summer.
